As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 4415-82-1, name is Cyclobutylmethanol, molecular formula is C5H10O, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. 4415-82-1
Step 1 : Into a 20-L 4-necked round-bottom flask was placed a solution of cyclobutylmethanol (1000 g, 1 1 .61 mol) in dichloromethane (10 L). This was followed by the addition of Dess-Martin periodinane (4683 g, 1 1 .04 mol) in several batches at 10-15 C over 120 min. The resulting solution was stirred for 2 h at room temperature and then quenched by the addition of 20 L of cold, saturated aqueous sodium bicarbonate solution. Solids were removed by filtration and washed with 5 L of dichloromethane. The filtrate was extracted with dichloromethane. The organic layers were combined, dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column and eluted with DCM:PE (2:1 ). This resulted in 100 L of cyclobutanecarbaldehyde in dichloromethane and petroleum ether solution.
The chemical industry reduces the impact on the environment during synthesis 4415-82-1, I believe this compound will play a more active role in future production and life.
